Question

Sketch the graph of
F(x)=2^x^-1

Answer 1

F(x)=2^x^-1 =

f(x) = 2^(1/x)

Answer 2

Make an x-y chart, from -2 to 2 and plot

Answer 3

*-1 to 1

Answer 4

Well te part i dont get is when you get negative exponents .i have to give atleast 5 points on the graph

Answer 5

2^-1 = (1/2)

Answer 6

The number (2/1) is flipped to (1/2)

Answer 7

So. Put it under 1 and then solve he exponent?

Answer 8

No, you want to solve for y. Lets make x=-1

y=2^(1/(-1))

Answer 9

when x=-1, y=(1/2)

Answer 10

(1/-1) = -1.

2^-1 = y = (1/2)

Answer 11

Now make x=0

Answer 12

I got1/2

Answer 13

Wha?

Answer 14

2^(1/0) =2^infinity = undefined

Answer 15

you cannot divide by 0

Answer 16

2^(1/1) = 2^1 = 2

Answer 17

So we got (-1,0.5) and (1,2)

Answer 18

If i put 1 in the equation, i get 2^0 whic is 1

Answer 19

No, 2^(1/x).

(1/1) = 1 ; 2^1 =2

Answer 20

http://www.wolframalpha.com/input/?i=y%3D2^x^-1%3B The graph should look like this

Answer 21

Thin makes nonsense

Answer 22

No sense

Answer 23

Are you sure you typed the equation correctly?

Answer 24

Please go slow

Answer 25

It's not 2^(x-1) is it?

Answer 26

No

Answer 27

I wish i could draw it

Answer 28

@ajprincess

Answer 29

You there?

Answer 30

yup I am.

Answer 31

x^(-1) can be written as 1/x
